The hermangrass has slowly crept into the waters of the Ichthy River, and has become the runanchor. Because of a lack of predators in these waters, the runanchor flourished and grew many times its original size.
Much of their form consists of a single, thick stalk which ends in the grass's large berry. Because of the heaviness of this object, the leaves have evolved into a wide lily pad-like shape to displace its weight and thereby keep afloat.
Rather than its ancestors' method of growing new gems on their leaves, the runanchor instead grows stolon, which end in a heavier gem than its predecessors. These "runners" are light enough to be significantly weighted down by the gems, forcing them into the riverbed. After about a week of physical contact with the bed, it takes root and begins to sprout another runanchor, still attached to the mother-plant. This can create small "forests" over time, much like Earth's alder trees or strawberries can do.
